[TowerTalk] beverage question

I'm thinking of having several beverages start at the same feedpoint, probably
with separate feedlines but perhaps with a remote switch. Which of those isn't
relevant to this question, I don't think but I didn't want you to think I had
one coax connected to several beverages at once. But, having them start at the
same point, probably with the same ground rod, then fanning out in their
separate directions.is there any reason not to do it this way? Any degradation
of performance by doing it this way, etc.? They will be at least 30 degrees
different in orientation, one from another.
Related: When beverages cross, I've heard that several feet of separation
should be sufficient to avoid interaction. Any comments on this? Any minimum
crossing angle to avoid interaction or anything like that?
Tnx. -- Rich, KE3Q
